Most offices use a rule of thumb from the 60s - selecting an average temperature based on the metabolic rate of a middle aged man. The metabolic rate is how fast your body burns energy and generates heat as a result.

As a result, the air-con is set too high, as women tend to have a lower metabolic rate than men - meaning they need more warmth.

In short, your air-con is sexist, as it's based on a gender bias that no longer exists.
